Ingeniously recovering damaged files in the XP system

Q: My computer's operating system is Windows XP. Recently, the hard disk has failed. I can't figure out whether it is a physical bad track or a logical bad track, but I am sure that I am storing it. Some files under the D drive are damaged. Is there any way to help me find these files?
A: You can use some special repair tools to repair your damaged files, or you can use them on the XP system. These files are fixed at the command prompt, provided that the data still exists and is not overwritten by other data. Take the example of repairing the Back.txt file in the root directory of your D drive. The operation method is: Click “Start →Run”, enter “ldld;CMD” in the run input box (without quotes) and press Enter. At the command line prompt that pops up, type “Recover d:\\Back.txt” (without quotes) and press Enter. The recovery process cannot be stopped and one file should be restored at a time. If your hard drive does have physical bad sectors, using this method will lose some of the data stored on bad sectors. You can edit or re-enter the missing information after restoring the file.
